I am part of the Marketing team at HP Tuners. We are constantly working on expanding our support and have recently added Nissan to our supported vehicle list!
For those of you that have not heard of HP Tuners we provide vehicle calibration solutions for the professional tuner, and for the hobbyist that is learning how to tune on their own.
If you are interested in learning more about our MPVI2 interface and VCM Suite 4 software, please visit our website - https://www.hptuners.com/
You can also feel free so send me a pm on here with any questions or concerns, and I will do my best to keep an eye out for posts related to our product.
